Poecilotheria regalis — the Indian Ornamental Tarantula — is one of the most visually striking arboreal theraphosids in the hobby. Native to the Eastern Ghats of India, this fast, defensive, and medically significant species rewards experienced keepers with years of impressive display. This guide covers everything you need to house, feed, and understand P. regalis correctly.
QUICK ANSWER — WHAT DOES POECILOTHERIA REGALIS NEED?
P. regalis requires a tall arboreal enclosure (minimum 18"H × 12"W × 12"D), temperatures of 75–82°F, humidity of 60–75%, vertical cork bark hides, a shallow water dish, and prey every 10–14 days. It is suited to intermediate and advanced keepers only.
- Enclosure: Tall arboreal, front-opening, 18" minimum height
- Temperature: 75–82°F (24–28°C) daytime
- Humidity: 60–75% RH with a light moisture gradient
- Feeding: Every 10–14 days (adults); 5–7 days (juveniles)
- Experience level: Intermediate to advanced keepers only
- Venom: Medically significant — not a handling species
Species Overview & Natural Habitat
Poecilotheria regalis is a large arboreal tarantula endemic to the Eastern Ghats mountain range of peninsular India. In the wild it inhabits the hollows and bark crevices of tall deciduous trees, constructing a funnel-web retreat and emerging nocturnally to ambush prey. Its silver-grey dorsal pattern with complex yellow-and-black underside chevrons makes it among the most visually spectacular of all theraphosids.
The genus Poecilotheria contains 14 described species, all endemic to India and Sri Lanka. P. regalis is the most widely kept and best-documented, making it the logical entry point for keepers moving into Old World arboreals.

SUITABILITY WARNING
This is not a beginner species. P. regalis is exceptionally fast, defensively unpredictable, and possesses venom with documented cases of severe muscle cramping, sweating, and prolonged systemic pain. A minimum of 12–18 months experience with more forgiving species is strongly recommended before acquiring one.

As an obligate arboreal, P. regalis requires height over floor space. Front-opening enclosures are strongly preferred for adults.
| Stage | Minimum enclosure | Notes |
|---|---|---|
| Sling (under 1") | 6–8 oz deli cup | Cross-ventilated, slightly moist |
| Juvenile (1–3") | 6"H × 4"W × 4"D | Small cork tube hide |
| Sub-adult (3–5") | 12"H × 8"W × 8"D | Begin adult husbandry protocols |
| Adult (5"+) | 18"H × 12"W × 12"D | Front-opening strongly preferred |
How to Set Up a Poecilotheria Regalis Enclosure (Step by Step)
- Add 4–6 inches of substrate — coconut fibre, organic topsoil, or peat/coco mix.
- Position a cork bark tube vertically near one upper corner, base buried 1–2 inches in substrate. Expect thick silk within 48–72 hours.
- Add a cork flat or cholla wood as a secondary resting surface.
- Place a shallow water dish in the lower third of the enclosure. Change weekly.
- Ensure cross-ventilation — mesh on two opposing sides to create an airflow gradient.
- Allow 24–48 hours to settle before introducing the spider.
Temperature & Humidity Requirements
| Parameter | Ideal | Acceptable | Avoid |
|---|---|---|---|
| Daytime temperature | 75–82°F (24–28°C) | 70–85°F | Below 65°F / above 88°F |
| Night temperature | 68–75°F (20–24°C) | 65–78°F | Sustained below 60°F |
| Ambient humidity | 60–75% RH | 55–80% RH | Consistently below 50% |
| Substrate (base) | Lightly damp | Slightly moist | Wet or bone dry throughout |
How to Feed Poecilotheria Regalis
| Stage | Prey item | Frequency |
|---|---|---|
| Sling | Fruit flies, pinhead crickets (pre-killed) | Every 4–5 days |
| Juvenile | Small crickets, small dubia roaches | Every 5–7 days |
| Sub-adult | Medium crickets, medium dubia | Every 7–10 days |
| Adult | Adult dubia roaches, adult crickets | Every 10–14 days |
| Pre-molt / Post-molt | None — remove all prey | Resume 14+ days after molt |
CRITICAL — NEVER LEAVE LIVE PREY UNATTENDED
Remove all uneaten prey within 24 hours. Crickets and roaches will injure a molting or recently-molted tarantula. Wait a minimum of 14 days after molt completion before resuming feeding.
Molting — What to Expect
Pre-molt signs: prey refusal for 3–4+ weeks, abdomen darkening, retreat sealed with thick silk, reduced activity.
During molt: Do not disturb the enclosure. The process takes 30 minutes to several hours. Never introduce prey or mist while a molt is in progress.
Post-molt: Wait 14+ days before offering food. Fangs need time to fully harden. Sex the exuvia under magnification — look for the spermatheca between the anterior book lungs for females.
Handling & Venom — The Honest Guide
Poecilotheria regalis should not be handled. Documented bite reports describe severe muscle cramping, sweating, heart palpitations, and systemic pain lasting 12–36 hours. All maintenance must be performed with 12-inch tongs. Visually locate the spider before opening the enclosure — every time.
Common Health Problems
| Issue | Signs | Action |
|---|---|---|
| Dehydration | Shrunken, wrinkled abdomen | Refill water dish; lightly mist substrate corner |
| Dysecdysis (bad molt) | Incomplete shed, limbs stuck | Improve humidity; humid hide |
| Prey injury | Wounds on abdomen or legs | Remove prey; prevent recurrence |
| Chronic stress | Constant pacing, no hide use | Reposition cork tube to top; reduce light |
| Substrate mites | Tiny specks in substrate | Full enclosure clean; reduce misting frequency |
